Fiber Optic Cabling

The equipment uses fiber optic cabling between the low voltage control and the
medium voltage circuits. You should never need to change the routing of the fiber
optic cables.

Each end of a fiber optic cable has a connector that plugs and latches into its
respective location on a circuit board. To disconnect a fiber optic cable, depress
the ridged plastic tab at the end connector and pull. To install a fiber optic cable
insert the fiber optic port of the circuit board so that the plastic tab latches into
place.

If you must replace fiber optic cables, be careful to prevent the cables from
straining or crimping as a resulting loss in light transmission will impact
performance.

The minimum bend radius permitted for the fiber optic cables is 50 mm (2.0
inches).

When installing the fiber optic cable, match the connector color at the end of the
cable with the connector socket color on the circuit board.
